In accordance with NFPA 409, aircraft hangar shall be provided with automatic sprinkler protection as specified chapter 12 (Group I Aircraft Hangars Unfueled).
The Aircraft hangar it's a fabricate woven polyester base cloth with PVC coating and a weld able PVDF finishing, inflatable model. ( 295,28 ft x 300,56 ft. )
Beacuse of its construction, It's difficulty of installing automatic sprinklers, beacause it's not possible to install an structure for the installation of sprinklers.
My question is:
Can the aricraft hangar protection be installed with monitors nozzles instead of the automatic sprinklers systems?
